Known for his quick speed and big play ability, Coach Tom Landry called him “Our Home Run Hitter. I’ve never seen a guy who could adjust to a ball in mid-air like Tony. He is a very explosive player---the type who can turn a short play into a big play in a hurry, because he has excellent running ability and speed.”

Hill became the number one receiver when Pearson retired after the 1983 season.[2] His best season statistically came in 1985, where he caught 74 passes for 1100 receiving yards and 7 touchdowns.[2] He eventually became one of the top wide receiver in the NFL from 1978 to 1985, and was dubbed the "Thrill" and "Dial 80", because of his explosiveness and ability to make big plays. A three-time Pro Bowl selection, during his ten-year career with the Cowboys, Hill led the team in both receptions and yardage for nine straight years. He never played in a Super Bowl again, but played in 10 more postseason games. One of the better performances in his career was in a 1982 divisional playoff game against the Tampa Bay Buccaneers, when he caught 7 passes for 142 yards in the Cowboys' 38-0 win.

Hill finished his 10 NFL seasons with 479 receptions for 7,988 yards and 51 touchdowns in 142 games. He also had 26 100-yard receiving games, rushed for 84 yards, returned 27 punts for 268 yards, and gained 96 yards on 4 kickoff returns. For his career, he averaged 16.1 yards per touch and 16.7 yards per reception.

In 2000, he appeared as a contestant on the short-lived game showGreed. He did not win any money after he got sacked on his $500,000 question as the team's captain. The question was: Which four and their affiliates have the highest global market share? The 7 choices were General Motors, Ford, Honda, Volkswagen, Hyundai, Toyota, and BMW. Honda, BMW and Hyundai were the incorrect answers.

On June 23, 2011 (his birthday), Tony appeared on Good Morning Texas to promote the Market Street Allen USA Celebration, a Fourth of July celebration held annually the last weekend of June in Allen. In honor of headline entertainer Lou Gramm, Tony showcased his singing voice by performing a small portion of one of Foreigner's hit songs, "Hot Blooded."

He is the CEO of Legends Sports Promotions, Inc., a company that raises funds for charitable organizations through celebrity basketball, softball, and football games as well as golf tournaments. It also manages athletes for motivational and promotional events. He is currently employed by the City of Allen Texas Parks & Recreation Department as a Resource Development Manager.
